Dental sealants are tooth colored resin coatings that are usually applied to the grooves of the chewing surface of the permanent back teeth to help protect them from decay.
The chewing surfaces of the molar and premolar teeth have deep grooves that make them vulnerable to decay. Plaqueaccumulates in these areas, and the acid from bacteria in the plaque attacks the enamel, causing cavities to develop. Dental sealants provide extra protection for the grooved and pitted areas by providing a smooth surface covering over the fissured area.
